REFRlGERATlNG-CAN.

SPECIFICATION forming part ofLetters Patent No. 256,566, dated April 18, 1882. w Application filed September 7, 1881. (No model.)

To all whom it may concern:

Be it known that I,JosEPH HEFELEY, Sn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State 5 of Pennsylvania, have invented certain new and useful Improvements in Refrigerating- Oans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled set forth, and particularly pointed out in the claims.

In the accompanyingdrawing, similar letters 2 5 t referenceindicate like parts of the invention. A represents the interior of a can having smooth straight sides and a converging neck, D, as shown. A is an outer sheathing of heavy corrugated iron, the corrugations shown 0 by the letter a.

D represents a malleable-iron casing forming a continuation of A, and fitting around the neck D so as to leave a non-conducting air-space, E. This casing D is also strengthcued and protected by corrugations (1.

The mouth B of the can is of ordinary construction; but the cap or cover 0 is double, and has a non-conducting air-space, 0, formed by the concavo-convex top a e. A vent-tube, I),

extends through the air-space in the top, and 0 is provided at its lower end with a strainer,

b. A metallic ring, c, is secured to the outside of the cover 0 to protect it from abrasion in handling, and an ordinary ball or handle, 0, for convenience in removing the cover, is also pro- 4 5 vided.

In operation the cover is removed and the can filled with milk, cream, or any liquid, the cover is then replaced, and any gas or animal heat contained in the fluid escapes through the vento tube b.

The contents are protected from extreme changes of temperature by the air-spaces O E and the non-conducting air-spaces in the corrugations to around the body of the can. These 5 corrugations also greatly strengthen and brace the can during handling while it is filled, and materially add to the life of it.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

1. A refrigerator-can consisting of the body A and neck D, re-enforced by the corrugated sheathing A (t D d, in combination with the cover 0, having concave-convex top 0 e. venttube 1), strainer b, and protecting-ring 0, substantially as set forth.

2. In a refrigerating-can, the cover 0, having the concavo-convex top 0 e, in combination with the vent-tube I), having strainer 72 and protectin g-rin g c, substantially as set forth.

In testimony whereof I at'fix my signature in presence of two witnesses.
